Ted Crocker has a good video on soldering piezos that might help.  Sometimes it's easier to absorb the concept when you can watch it being done.

If you already have wires on your piezos they are sufficient.  If you need them longer, just solder on extensions.  If they're bare piezos... yeah, that can be a bit tricky.  I've not yet mastered soldering bare piezos myself.

 Ok, thanks again Wayfinder. I may need to try and solder these wires direct. 

 Just have a cheap solder gun and it's a bit rough to not fry the ceramic. The peizos are cheap though so I can practice some :)

Comment by Wayfinder on June 26, 2016 at 7:30pm

Just the opposite, I believe.  The thicker the wire, the more room for current flow and thus less impedance.  Well, not less because you're going to still have the original impedance, but less than thinner wire or less conductive wire.

Comment by Murdoc_420 on June 26, 2016 at 3:47pm

About the wires.

 The wires I got at the hardware store are quite a bit thicker than the wires coming off the peizos.

 Would that cause a lot of empedance?

Comment by Paul Craig on June 21, 2016 at 12:23pm

If that isn't it, it must be in the jack/cord.

Comment by Paul Craig on June 21, 2016 at 12:20pm

Murdoc, did you wire the piezo's in series or parallel?

Series would greatly reduce the impedance of the piezo's and result in low volume. Would be positive to positive of one piezo and negative of that piezo to positive of other piezo and the same for thethird piezo with it's negative to ground.

Parallel would be all piezo's positives wired together to hot and all negatives wired together going to ground would just slightly reduce impedance and have great sound and ample volume.

Yeah I could do a mag but the piezos keep it so 'rustic' :D

 The git works, but can barely be heard.

Comment by Wayfinder on June 20, 2016 at 6:07pm

BTW regarding how to get more sound to the amp:  replace the piezos with a mag.

Comment by Wayfinder on June 20, 2016 at 6:06pm

I'm stumped then.   Sounds to me like an amp problem-- functional enough to play the iPod but not enough to reproduce the guitar signal.  I know these work because I've used them myself, but sounds like that one is borderline.  I can't think of anything else.  The git works, you've checked the cable, the iPod works, but the git doesn't through this board.  Does that sum it at this time?
